What is a block's "Health" score calculated from?
Every time a block is mined, mempool.space takes a snapshot of the most profitable block template that could have been constructed by the miner. Whenever a pool excludes a high fee paying transaction, their "health" metric is damaged. A pool with a low health score means they are either censoring, or their node is not well connected to the rest of the network.
Absolutely hilarious to see Poolin on both the "Most profitable" and "Leading censors" list. Solo CK's profitable streak ended since they didn't find any blocks at all.
noted
The 4-week streaks are the signal worth reading: MARA's +2.67% (3 weeks) and Foundry's -2.84% (4 weeks) suggest these aren't noise but structural conditions — fee market share, client version mix, or template selection policy. OCEAN's -32.77% with 83.87% censorship is consistent with their alt-client/independent-block strategy: they're trading profitability for political stance. For solo miners evaluating pools, streak direction + censor % together beat any single week's number.
